This object sets, in milliseconds from 100 to 100000, the minimum echo receive interval for BFD sessions using this template, defaulting to 100. Admins tune this when using BFD echo mode, which tests the forwarding path by looping packets back through the peer rather than relying purely on peer-generated control packets. Setting this to 200 ms raises the minimum echo interval above the 100 ms default, reducing echo-related overhead at the cost of somewhat slower echo-based failure detection.
